Description

本発明は、漏出化学物質除毒用中和吸収剤及びその製造方法と、これを充填した中和器に関し、より詳細には、研究室や実験室または産業現場で不意に発生することがある塩酸、酢酸、フッ酸、硝酸、硫酸、水酸化ナトリウムや水酸化カリウム溶液、過酸化水素、アンモニア水、トルエン、またはベンゼンなどの酸性、塩基性、及び／又は有機化学物質の漏出事故時に漏れた化学物質の種類や特性にかかわらず、迅速かつ安全に効果的に中和処理することにより、２次事故を防止するのに有用な漏出化学物質除毒用中和吸収剤及びその効果的な製造方法と、その除毒用中和吸収剤が充填された中和器に関する。 TECHNICAL FIELD The present invention relates to a neutralizing absorbent for detoxification of leaked chemical substances, a method for producing the same, and a neutralizer filled with the same, and more particularly, to a neutralizer that may occur unexpectedly in laboratories, laboratories, or industrial sites. Accidental spills of acidic, basic, and/or organic chemicals such as hydrochloric acid, acetic acid, hydrofluoric acid, nitric acid, sulfuric acid, sodium or potassium hydroxide solutions, hydrogen peroxide, aqueous ammonia, toluene, or benzene Neutralizing absorbents for detoxification of leaked chemical substances useful for preventing secondary accidents by neutralizing quickly, safely and effectively regardless of the type and characteristics of chemical substances, and effective production thereof It relates to a method and a neutralizer filled with a neutralizing absorbent for its detoxification.

近年、亀尾と清州のフッ酸漏出事故、尚州の塩酸漏出事故など産業現場での化学物質の漏出事故により多くの財産と人命被害が発生しており、様々な種類の化学物質を多く使用する大学や研究機関の研究室や実験室でも実験中において化学物質の漏出事故が頻繁に発生している。 In recent years, chemical leakage accidents at industrial sites, such as hydrofluoric acid leakage accidents in Gumi and Cheongju, and hydrochloric acid leakage accidents in Sangju, have caused a lot of damage to property and human lives, and many kinds of chemical substances are used. Leakage accidents of chemical substances frequently occur during experiments in laboratories and laboratories of universities and research institutes.

このような化学物質漏出事故の発生時に初動措置の不在は、さらに大きな２次事故につながるため、迅速かつ適切な初動措置は、国民の財産と人命被害を最小限に抑える上で特に重要である。 In the event of such a chemical leakage accident, the absence of initial measures will lead to an even larger secondary accident, so prompt and appropriate initial measures are particularly important in minimizing damage to property and human lives. .

現在、化学物質の漏出事故時の初期対応方法は、手作業によるフェンス設置や吸着剤または中和剤を散布することが一般的であり、前述した亀尾のフッ酸漏出事故では、消防士がフッ酸に水を噴射することにより、事故がさらに大きくなる事態を招いた。 At present, the initial response method in the event of a chemical leakage accident is generally to manually install a fence or spray an adsorbent or neutralizer. Injecting water into the acid led to an even bigger accident.

従来の化学物質の漏出事故の処理は、酸性化学物質の漏出時には、塩基性化学物質で中和処理し、塩基性化学物質の漏出時には、酸性化学物質で中和処理し、有機化学物質の漏出時には、吸着剤や吸収布を用いて処理する、それぞれ別途の厳格に区分された方法が適用されている。 In the conventional treatment of leakage accidents of chemical substances, the leakage of acidic chemicals is neutralized with basic chemicals, the leakage of basic chemicals is neutralized with acidic chemicals, and the leakage of organic chemicals is neutralized. Sometimes separate and strictly differentiated methods of treatment with adsorbents or absorbent cloths are applied.

漏れた化学物質の種類と性状を知らなかったり、誤った中和器を使用する場合、さらなる事故につながりかねない。また、従来の酸性化学物質の漏出時に使用する中和器の場合、過量使用時に塩基性化学物質が残留し、２次汚染を引き起こすおそれがある。 Not knowing the type and nature of the leaked chemical or using the wrong neutralizer can lead to further accidents. In addition, in the case of a conventional neutralizer that is used when acidic chemicals leak, basic chemicals may remain when used in an excessive amount, causing secondary pollution.

従来の酸性用又は塩基用中和器は、使用時に酸と塩基の反応による水が生成されるため、反応しない中和薬品と水が混在することになるため、拡散のおそれを常時内包している。 In the conventional neutralizer for acid or base, water is generated by the reaction of acid and base during use, so the non-reacting neutralizing chemical and water are mixed, so there is always the risk of diffusion. there is

また、漏出化学物質の種類に応じて中和器を区分選択して使用しなければならないので、その選択過程により初動措置が遅くなるとともに、適正使用量を初動措置者が正確に判断することが困難であり、迅速かつ適正な中化除毒が行われていないため、さらなる財産と人命被害が発生する可能性が大きいという問題点がある。 In addition, since the neutralizer must be classified and used according to the type of leaked chemical substance, the selection process slows down the initial action and makes it difficult for the person taking the initial action to accurately judge the appropriate amount to use. It is difficult, and there is a problem that there is a high possibility of further damage to property and human life due to the lack of prompt and proper neutralization and detoxification.

したがって、従来の技術的限界は、漏れた化学物質の種類に応じて酸、塩基中和反応による中和器を選別して使用しなければならないという点と、有機化学物質の漏出事故時には、その使用において明確な制約が存在する。 Therefore, the conventional technical limitation is that the neutralizer should be selected and used according to the type of leaked chemical substances, and the neutralizer should be selected according to the type of leaked chemical substances. There are clear restrictions on their use.

化学物質の漏洩時の初動措置として除毒のための典型的な従来技術としては、下記のものが挙げられる。 Typical prior art techniques for detoxification as an initial response to chemical spills include the following.

韓国登録特許公報第１０－１６０５５８２号（２０１６．０３．１６．登録）が挙げられ、塩基性化学物質の中和のための中和剤が内蔵された蓄圧式本体容器と、本体容器に装着される中和剤噴射用レバーと、放射ホースと、安全ピンを含む放射部と、を含み、蓄圧式本体容器には界面活性剤が含まれ、本体容器は、７～９．８ｋｇｆ／ｃｍ２の圧力状態であり、中和剤は、クエン酸、フマル酸、希塩酸、酢酸、またはこれらの任意の混合物である漏出塩基性化学物質中和用中和装置が提案されている。 Korean Patent Publication No. 10-1605582 (registered 2016.03.16) includes a pressure accumulator main container containing a neutralizer for neutralizing basic chemicals, and a main container attached to the main container. a neutralizing agent injection lever, a radiation hose, and a radiation part including a safety pin; the pressure accumulation type main container contains a surfactant; A neutralization device is proposed for neutralizing leaking basic chemicals, which is under pressure and the neutralizing agent is citric acid, fumaric acid, dilute hydrochloric acid, acetic acid, or any mixture thereof.

また、韓国公開特許公報第１０－１９９６－００１００３０号（１９９６．０２．１４．公開）には、漏れた少量の酸や有毒ガスなどを処理除去する酸中和剤組成物として中和反応時に緩やかに反応しうる塩基性物質（トリエタノールアミン）と漏れるガスや中和反応時に発生するガスを容易に吸収中和するガス吸収剤（ジエタノールアミン）及び反応状態を肉眼で識別できる機能を持つアリザリンレッドなどで組成させた酸中和剤組成物が提示されている。 In addition, in Korean Patent Publication No. 10-1996-0010030 (published on February 14, 1996), an acid neutralizer composition for treating and removing a small amount of leaked acid or toxic gas is gently used during the neutralization reaction. Basic substance (triethanolamine) that can react with gas, gas absorbent (diethanolamine) that easily absorbs and neutralizes leaking gas and gas generated during neutralization reaction, and alizarin red that has a function that allows the reaction state to be identified with the naked eye, etc. An acid neutralizer composition is presented comprising:

また、韓国公開特許公報第１０－１９９７－０００９８３１号（１９９７．０３．２７．公開）には、少量の酸や有毒ガス等を処理除去する酸中和剤組成物として中和反応時に緩やかに反応しうる塩基性物質（無水炭酸カルシウム、無水炭酸ソーダ、酸化マグネシウム）と漏れたガスや中和反応時に発生するガスを容易に吸収中和するガス吸収剤及び反応状態を肉眼で識別できる能力を持つＢ．Ｔ．Ｂ（色素）などで組成させた粉末状酸中和剤組成物が提案されている。 In addition, in Korean Patent Publication No. 10-1997-0009831 (published on March 27, 1997), an acid neutralizing agent composition that treats and removes a small amount of acid, toxic gas, etc., reacts gently during the neutralization reaction.

B. T. A powdery acid neutralizer composition composed of B (pigment) and the like has been proposed.

しかし、前記従来技術は、すべて酸性または塩基性化学物質の特定の種類に限定して適用できるだけで、酸性及び塩基性化学物質の両方に併用できるものではなく、さらに有機化学物質の除毒は可能でないという制限がある。 However, all of the above prior arts can only be applied to specific types of acidic or basic chemicals, and cannot be applied to both acidic and basic chemicals, and can also detoxify organic chemicals. There is a restriction that it is not
